ABSTRACT:
A system for aerating in a programmed manner the desired areas of a water pond to enhance the environment for marine life in the pond; said system including a propelled boat with an aerator mounted thereon and having direction control apparatus including a rotating beam-sending component, a plurality of beam-reflecting posts located in predetermined fixed relationship around the shore line of the pond, and a beam-receiving component mounted on the boat to receive the beam reflected back from each of the reflecting posts, whereby the position of the boat can be determined automatically by angle determining components combined with a microprocessor programmed to calculate by triangulation computation the position of the boat and produce a signal which is connected to a servo system which controls the direction of travel of the boat in its aerating path around the pond.
